SPECIFICATION forming part of Letters Patent No. 444,766, dated January13, 1891.

Application filed June 4, 1890. Serial No. 354,263. (No model.)

To all whom, it may concern.-

Be itknown that I, EDWARD POOLE, a citizen of theUnited States, residingatFordyce, in the county of Dallas and State of Arkansas, have inventeda new and-useful Machine Spoo1- Rack, of which the following is aspecification.

The invention relates to improvements in machine spool-racks,

The object of the present invention is to provide a spool-rack forsewing-machines adapted to hold a number of spools and designed to beplaced on the spindle of a sewing-machine after the manner of anordinary spool and capable of enabling spools to be readily inserted andremoved.

A further object of the invention is to provide a simple and convenientthread-cutter to facilitate the changing of spools for use on themachine.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a spool-rackconstructed in accordance with this invention and illustrating themanner of cutting thread. Fig. 2 is a similar view, the upper disk beingremoved. Fig.

is a central vertical sectional view and illustrating the position ofthe rack on the spindle of a sewing'machine. Fig. 4 is a detailperspective view of the tension device.

Referring to the accompanying drawings, 1 designates a spool-rack forsewing-machines, adapted to be placed on the spindle 2 of asewing-machine after the manner of an ordinary spool, and composed of alower disk or plate 3 and upper disk or plate 4, a central vertical tubeor stem 5, rigidly secured to the lower disk and having the upper diskremovably secured to it, and a series of vertical spool-spindles 6,rigidly secured to the lower disk-or plate 3 and arranged vertically,preferably concentric, with the central tube or stem 5, and adapted tofit in the ordinary opening of a spool 7. The upper end of the centraltube or stem 5 is provided upon opposite sides with feathers orprojections 8, and the upper disk or plate 4 is provided withoppositely-arranged slots 9, adapted to receive the feathers orprojections 8 of the central tube or stem and permit the upper disk orplate 4 to pass the same, and after the upper disk or plate has passedthe feathers or projections 8 it is turned to carry the slots away fromthe projections or feathers, and in order to prevent the disk becomingaccidentally displaced from the stem a key-plate 10' is employed, and isprovided with slots 11, similar to those of the upper disk or plate atto enable the key-plate to pass the feathers or projections, and whenthe key-plate is turned the feathers or projections 8 are brought intoengagement with notches l2 and the lower edges of the projection arebeveled, in order to more readily engage the notches 12 and prevent thekey-plate slipping and bringing the slots opposite the projections orfeathers.

The upper disk or plate 4, is provided with a circular opening 13,arranged near the edge or the periphery, and of suflicient size topermit a spool to readily pass through it, and the said plate or disk isadapted to be rotated to bring the opening 13 opposite any one of thespools to enable the latter to be readily removed from itsspindle. Thespools may rest loosely on the bottom plate or disk 3 and the feeding ofthe thread be entirely controlled by the sewing-machine; or tensiondevices 14 may be employed to retard the rotation of the spool. Thetension device 14 is composed of a centrally-perforated disk 15 and aspiral spring 16, having its opening arranged opposite the perforationof the plate and being secured to the disk, and the said tension deviceis adapted to be arranged on the spool-spindle, with the perforated diskengaging the lower end of a spool to hold the latter in engagement withthe top plate.

The lower disk or plate 3 has its edge or periphery 17 slightly upsetand arranged at an angle to the rest of the plate and shortened toprovide a knife-edge forsevering the thread, and preparatory to cuttingthe thread is engaged in an opening of a hook l8, projecting downwardlyand radially from the edge or periphery 19 of the upper disk or plate,and the said edge or periphery 19 is bent slightly downward tofacilitate the attachment of the hook, and the end of the wire forming ahook is bent upon itself and arranged at a slight angle to the stem ofthe hook to provide a gradually decreasing opening for the hook toengage the thread and prevent the spool rotating during cutting, and itwill readily be seen that after cutting sufficient thread hangs from thehook to enable the same to be readily disengaged.

The advantages of the spool-rack and the conveniences afforded by itwill readily suggest themselves, and it will readily be seen thatvarious grades and kinds of cotton and thread can be contained in therack, and one kind can readily be substituted for another on the machinewithout removing the spool in use, as has heretofore been necessary.

The use ofspool-raeks constructed in accordance with this invention isnot limited to sewing-machines; but is equally applicable to looms,Weaving-machines, and the like where spools of thread are employed; andI desire it to be understood that I do not limit myself to the precisedetails of construction herein shown and described, as I may withoutdeparting from the spirit of the invention make minor changes therein.

v Having described my invention, what I claim is 1. A spool rac'k formachi es, comprising the bottom plate, the tube or hollow stem securedto the bottom plate and forming a socket to receive the spindle of amachine and provided at its upper end with oppo sitely-disposed feathersor proj eotions having their lower edges beveled, the spool-spindles,the upper plate having oppositely-disposed slots, and the key-plateprovided with similar slots and having notches 12 adapted to be engagedby the projections, substantially as described.

2. A spool-rack having a socket to receive the spindle of a machine andprovided With the disk having its peripheryupset and arranged at anangle to the body of the disk and sharpened, substantially as described.

8. A spool-rack for machines, comprising the lower disk having itsperiphery upset and sharpened the hollow stem secured to the lower diskand forming a socket to receive the spindle of amachine, thespool-spindle, and the upper disk provided with hooks 18, adapted to beengaged by a thread, substantially as described. 7

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

EDWARD POOLE.
